Newtons Law of Gravitation

• Every particle in the Universe attracts every
  other particle in the Universe with a force that
  depends on the product of the two particle masses
  divided by the square of the distance between

Newtons First Law

• Every body continues in rest or in uniform motion
  in a straight line, unless it is compelled to
  change that state by forces impressed upon it
  (Christianson 292)

• The change in motion is proportional to the
  motive force impressed and is made in the
  direction of the right line in which that force
  is impressed.

  reaction or, the mutual actions of two bodies
  upon each other are always equal and directed to
  contrary parts.
